SPECIFICATION forming part of Iletters Patent No. 478,595, dated July12, 1892.

Application filed March 8, 1892. $erial No. 424,186. (No model.)

To aZZ whom it may concern:

Be it known that I, STEWART HAMILTON, a citizen of the United States,residing at lVeir, in the county of Cherokee and State of Kansas, haveinvented a new and useful Mine- Elevator, of which the following is aspecification.

This invention relates to improvements in mine elevators or cages, theobjects in view to being to provide an elevator adapted for raisverticallongitudinal section of a shaft, a cage constructed in accordance withmy invention being mounted therein and located be1ow the point ofdumping. Fig. 2 is a similar view, the cage being in the act of dumping.Fig. 3 is a detail of the cage. Fig. 4 is a transverse section thereof.Fig. 5 is a detail in perspective of one of the combined guides andyokes.

Like numerals of reference indicate like parts in all the figures of thedrawings.

The shaft is provided with the usual framework, consisting, as hereinshown, of the vertical uprights or posts 1, connected at intervals bytransverse bars 2, betweenwhlch and the posts 1 oppositely-disposedinclined braces 3 are located. Opposite the top of the shaft side bars4, wider than the bars 2, though corresponding therewith, are located,and from these side bars to the upper and lower ends of the frame-workvertical guide-sections 5 and 6 extend. The upper sections 5 and thelower sections 6 terminate short of each other at their adjacent ends,though, as shown, they are in vertical alignment, and each is but acontinuation of the other. The adjacent ends of each vertical pair ofsections 5 and 6 are beveled at opposite sides, so as to form anintervening space 7. From the lower sections 6 there extend upwardly andoutwardly 1nolined track-sections 8, the inner ends of which are aslight distance from the upper ends of the sections 6. Thesetrack-sections have their'upper ends pivoted by bolts 9 to the side bars4 and have their rear or lower ends removably secured by bolts 10, whichpass through the track-sections and into the bars 4. If desired, thesebolts 10 may be removed and the track-sections 8 swung to a verticalposition or where they are inoperative, and locked in such position byentering the bolts 10 into suitable holes 11, formed in the bars 4 forthis purpose.

In rear of the recesses 7 and having their' lower endspivoted by bolts12 is a pair of declining tracks or sections 13, the same ex tendingfrom a point in rear ofthe guides 5 up to within a short distance of thelower ends of the guides 4, but terminating short of the same, so as toleave an intervening space. The upper ends of the sections 13 areremovably secured by bolts 14, passed through perforations in thesections and into openings formed in the bars 4. By removing the boltsand swinging the sections 13 rearwardly they may be locked ininoperative position by reinsertingthe bolts in suitable openings 15,located in rear of said sections and formed in thebars 4. r

In constructing the frame-Work of the cage I employ a strong rectangularbase-frame 16, consisting of front and rear and opposite side bars, theends of which are joined andsecurely bolted together. Metal straps 17are bolted to I;

the upper and lower sides of this base-frame and arranged in pairs, andbolted between each pair of metal straps is an inclined hangerrod'18;

19 designates a superimposed suspensionbeam, and the same has embracingsaddles or straps 20, located near its ends, to which are securelybolted the upper ends of the suspension-rods just mentioned. The cablesfor raising and lowering the cage orelevator are secured to thistransverse superimposed suspension-beam. Guide-shoes 21 are secured tothe opposite ends of the beam 19 and centers of the opposite side barsof the base-frame of the cage. These shoes are U-shaped in cross sectionand somewhat snugly embrace the guides 5 and 6, upon which they areadapted readily to move.

A pair of standards 21 rise from the front and rear ends of thebase-frame, the latter standards being somewhat taller, preferably,

than the former, and each pair of standards constitute supports fortransversely-opposite bearings 24. In these bearings 24rock-shafts 25are journaled, and the same pass through eccentrics or eccentric-disks25.

26 designates a car-supporting frame, from the opposite sides of which,near the front and rear ends thereof, depend hangers 27. These hangersare connected by bearing-pins 28 with eccentrically-formed holes 29,formed in the eccentrics before mentioned, so that, as will be obvious,the frame 26 is capable of pivotal movement upon the eccentrics. Locatedbetween the rear pair of standards is a stop-block or bolster, the samehaving rests 31 at its opposite ends, upon which the rear eccentricsnormally rest. The rear eccentrics are connected at a relativelydifferent point m ne hangers to what the front eccentrics are, so thatas the front eccentrics move, so that their poi'n ts of connection withthe hangers are the front of the same, the pivotsof the rear ececntricswill be at the upper sides and hence the frame 26 would be tippled ortilted, so'as to dump anythingtherefrom, In bearings 32, with which theopposite side bars of the frame 26 are proyided, a pair of shafts 33 arej,oi' 1 rnaled,'the ends of which ext d. yo'li h ll 26 and o rpostesides o h verna ui a d, here h y re providedwith loose rollers 34:,adapted to rotat'efofver the 'oppositesides of the said vertical guides.

' shown in detail in Fig 5, the saddlesor. strapsand the guides at theopposite ends of the earn 19 may be formed integral.

Inoperation, if it is desired to raise coal from the pit, the sectiOnsSand 13of the track are. swun 9 t inclined ss ons; er to: fore describedas their operative positions,) and can 35 is mounted pOn the frame 26and locked against movement thereon. As theeler o scend h front a f oler passes underj the tracksS, while therear pair connein contact withthe rear tracks 13, are fleqted rdm th t econ s O r a d: pon h r ck's.pre u de mov n a hs upper i ertic'al guides 5 having passedthrough the:recesses intervenin g between the tracks 8,

and '13 and theguides 5 and 6. A continued movementu'pon the part of thecage causes the front eccentrics to. rotate, so as to lower the froln'tlend of the frame 15 and raise the rear en'd thereof, and. thus the coalis dis ohargcdffrem the car. i nto any waiting reeep l i W e e was, hswel ningover the'tra'ek-sections 8 and 13 return thefcaifand, the frame26to their proper posisens," Erem'this it will be seen that coal maybeleaded into the carfsat the bottom of the pit orat any intermediatepoint andth'at the same maybe automatically delivered as soon as thecagereaches the upper end of the shaft. When it isdesired to throw thetilting m'ech'anism'out'of operatiomthe tracks 8 and 13 are swung totheir inoperative positions and lochedby the means heretofore described,

. claim is and it will thus be seen that the cage can pass up and downupon the guides 5 and 6 as if the latter were continuous, and istherefore safe for the transportation of the miners and others from themouth of the shaft to the bottom of the shaft or any intermediateportion, or from thence back to the mouth of the Having described myinvention, what I l.
